What is the fission theory?
The Fission Theory: This theory proposes that the Moon was once part of the Earth and somehow separated from the Earth early in the history of the solar system. The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.
Who came up with the co-accretion theory?
Co-accretion Theory – Stephen himson
What is missing from the co-accretion theory of lunar formation?
An explanation accounting for the differences in density between the Earth and moon. …
What is a capture theory?
The Capture theory postulates that government regulation is effected in order to meet the needs for regulation of industry, i.e. legislators are captured by the industry, the regulation organization will be controlled finally by the industry, i.e. lawmen are captured by the industry.
Where does most of the water on Earth come from?
Multiple geochemical studies have concluded that asteroids are most likely the primary source of Earth’s water. Carbonaceous chondrites–which are a subclass of the oldest meteorites in the Solar System–have isotopic levels most similar to ocean water.
What made the water disappear?
The warmth of the sun changes the liquid into water vapor that we can’t see. After awhile the water vapor condenses and forms into clouds. Eventually, the water comes back to the ground as rain or snow or hail. Over time, the water evaporates again.
Why is water important for life?
Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent,” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients

Why is it called H2O?
The scientific name for water is H2O. It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O). There are millions of these molecules in one drop of water. The form water takes depends on the movement of the water molecules
What are the two types of water?
Water molecules exist in two forms — different, but with almost identical physical parameters. Researchers refer to these two forms as ortho-water and para-water
What is H2O the chemical symbol of?
Save This Word! The chemical symbol (see also symbol) for water. Each molecule of water contains two atoms of hydrogen (H) joined to a single atom of oxygen (O).
How H2O is formed?
The actual reaction to make water is a bit more complicated: 2H2 + O2 = 2H2O + Energy. In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2). Energy will be released in the process.
What type of reaction is the formation of water?
synthesis
Is the formation of water endothermic?
The formation of water is substantially exothermic. The reaction that forms water (from the elements it is composed of) is the combustion of hydrogen, which is clearly exothermic!
What is 2CO2?
2CO2. It’s read as 2 Carbon dioxide molecules. CO2 contains one atom of the element Carbon and 2 atoms of the element Oxygen. A number that comes before a compound or molecule e.g 2 in this case is indicating that there are 2 carbon dioxide molecules.
Is 2CO2 a gas?
Carbon dioxide is a naturally occurring substance composed of one atom of carbon (C) and two atoms of oxygen (O2). Its chemical formula is CO2. CO2 is gas under normal conditions.
What is difference between CO2 and 2CO2?
Carbon dioxide is composed of 1 atom of carbon and 1 atom of Oxygen, whereas dicarbon dioxide is composed of 2 carbon atoms and 2 oxygen atoms
What is the largest molecule?
The aptly named titin weighs in at a molecular weight of 3 million and consists of a continuous chain of 27,000 amino acids, making it 20 to 50 times larger than the average-size protein.
Which is the longest chemical formula?
(C18H24N2O6), a miticide and contact fungicide used to control powdery mildew in crops. The IUPAC name for Titin. This is the largest known protein and so has the longest chemical name. Written in full, it contains 189,819 letters.

What is the smallest molecule in the human body?
A cell is the smallest independently functioning unit of a living organism. Even bacteria, which are extremely small, independently-living organisms, have a cellular structure. Each bacterium is a single cell.
